to the value, o't the key, and then the continued downward movement of the key Vwill 'operate the space trame 2l, and this, through the lever 93 and the connections described, will turn the escapement shalt. l-t to throw one pawl out of engagement with the escapeinent rack and the other pawl into line therewith, so that the lett feed oit' the transmitting gear carriage will be etlected. The feed toward the lett is step by step, one step heing accomplished for each delnession ot' one ot' the keys, and at each action one ot the transmittii'ig seglnents will be 'thrown into engagement with the teeth ot the selector, and it a number ot keys are operated in succession, the trai'isniitt-ing wheels or segments will he turned in succession or one after the other, and thus by the let'tward movement of the carriage, they will be engaged with the selector' in different angular positions, according to the values ot the keys operated, it being understood that tor each operation ot the key the selector is turned to ditterent angular positions, so that upon the release oit the key the transmitting elements will he set back in the dit-ferent relative positions to each other, according to the dit'- iierent positions assumed by the selector when the several transmitting wheels or segments engage therewith. The desired number of transmitting wheels or seguients having been engaged with the selector, the next action is to transfer these values onto the totalizer wheels. rl`hese wheels are indicated at 2T, and are normally disengaged trom the transmitting gears or wheels, and` for accomplishing this transferring action, a hand lever 28 is employed connected with a shat't 29 geared through the toothed wheel 30 and the wheel 3l, with a shaft suitably mounted in the trame, the connection being made through an interposed spring clutch i 3, 'ny which, when the handle is turned ono way, motion will be communicated to the sha'tt- 32, whereas when the handle is reversed, no movement will he communicated hecause the clutch on this moveu'lcnt will slip. The shaft 32 is connected through gears 33, 34, with a cam shaft 85 upon which is mounted a cam 36. The rotation ot this cam, when the .handle is drawn toryward, will operate upon a. roller il? carried by a lever 38 pivotally mounted at 3S) in the frame, .the forward end ot said lever heilig connected through a link 40 with an arm il fixed to the shaft 3, so that it will be seen the operation oi the hand lever will, through the connections described. move the selector segment; in the direction ot the arrow, Fig. 3, and thus turn all ot' the t-ransmitting` gears which may he in engagement therewith upwardly on the lett Figs. 3 and 4; to make these gears engage the gears of the totalizer wheels Q7, result-ing in transterring the values onto these totalizer wheels. -'l"he position ot the selector' memher 6 with relation to the transmitting wheels G in their normal position is that which is necessary tor adding the number t). When one ot' the numeral keys is depressed, the shatt 3 and the selector (l mounted thereon will be turned through a distance corresponding to the dill'erenee between t) and the tigure struck; that is..` depression ot the t) key will not rotate the shatt 3 andthe selector (l at all, but will simply operate the escapement. Depressing the 8 key will raise the selector one tooth, and so on.

.litter the values have been transferred to the totali/:er wheels by the operation of the trzmsmitting e'ears, the further rotation ot the cam shat't 35 will cause a cam ft-2 to act on a roller -l-fi ot the lever arm lll, and this, through a. link il-5 and bell crank lever 4G, will move the pawl lf3 to torce the transmitting wheel. carriage toward the right one step to disengage the transmitting wheels from the totalizer wheels and make them occupy positions in line with the spaces between said totaliaer wheels. These transmitting gears, however, will still remain in e11- gagement with the selector. 'ihc further rotation ot the cam shait't 35 will now bring the cam 3C into engagement with the roller t7 on the lever 38, and give a reverse movement to said lever from that which the cam 3i; previously gave it, with the result that through the link et() and arm tl the selector .segment will he returned to normal position, and the transmitting gears to their set back ptsition, namely, their respective angular positions which they assumed as a result of the lirst operation of the ligure keys, the turning ot' the selector, and the lateral movement et the transmitting gear carriage. The

further forward movement ot the handle now acts through a cam 4S on the shaft 35, and a roller 4S on the lever or arm 49 to return the carriage lever i7 toward the righ."J by means ofthe link 50, resulting in the return ot the whole group oli' transmitting gears to their disengaged position at the right ot the plane ot' the selector, as shown in Fig. l. This action withdraws the transmitting gears from beneath the totalirier, so that they will then occupy' their original position at the right ot these totaliL/.ers and the selector. rthe position of' the transmitting gears which have heen displaced into angular position and are engaged with the selector t5 when that selector is in its normal position is such that they will pass under the rigid arm 5l when the transmitting gear carriage is movedl to the right from under the totalizer. .fl-rt the completion (it this withdrawing` action toward the right, a cani 52 on the cam shatt 35 acting on the roller 53 of the lever 54 will operate the said lever, which, through a link 55, and an arm 5G on the shaft S, will rotate the said shaft, and

.so that when the operation. is completed,

we will have thc selector back in normal position but engaged by a plurality of transmitting gears occupying different angular positions in respect to the shaft 8, according to the values ot the operated keys. Upon the operation ot' the handle, the selector 6 will be moved in the direction ot the arrow, Fig. 3, and the ditterently set transmitting gears will engage the totalizer wheels and transfer thereto the diterent values, according to the angular positions of the transmitting gears. The transmitting gear carriage, at the completion of this transferring action, will now be shifted one space to the right by the cam 4t2, and the cam 3Gthen acting, will return the selector to normal position and the transmitting gears to their set vback angular positions, and following this action, the cam 48 will return the whole group ot t lansmitting gears tothe right to the position shown in F ig. il, and :following this the differently set transmitting gears will be borne upon by the returning arm 5T, and they will be turned about the axis S trom their diiterent angular positions to be lined up by contacting with the under side of the bar 5l.

In order to eliminate errors, I provide a key at (3G which is connected with the bell crank lever -l-t. By the operation ot this key the carriage ot the transmitting gears may be shifted to withdraw the said gears out ot connection with the totalizer whtels, and to set them opposite the spaces between the said totalizer wheels, so that, upon the operation ot the hand lever, no transferring action will take place.

The totalizer may be of any approved type. I prefer to arrange the transmitting wheels in a position to add the number 9 when in normal relation to the other parts, because in this way I can employ such a connection between the keys and the shaft otl the selector that the movement o'l the shaft under the action ot the keys will be in the saine direction with that imparted to the sha't't when the hand lever is operated. In other werds, when a key is operated, the pin on its hub will strike the pin on the shaft, and turn the same toward the let't at its upper part, and when the hand lerer is operated, the shat't will turn in the same direction, its pin moving away from the pin on the hub of the key lever,l and thus having no contiict therewith. tepeated subtractions may be eilected by pressing in the subtracting key and the multiplying key, and operating the handle.
